How to know whether an auto hide animation has been started or ended in WinForms Docking Manager?

// Handles event AutoHideAnimationStart
private void dockingManager1_AutoHideAnimationStart(object sender, Syncfusion.Windows.Forms.Tools.AutoHideAnimationEventArgs arg) 
{
    if(arg.DockBorder == DockStyle.Left || arg.DockBorder == DockStyle.Right)
       if (arg.Control.Width == 0)
           Console.WriteLine("Started Animation-Showing control");
       else
           Console.WriteLine("Started Animation-Hiding control");
    else if (arg.Control.Height == 0)
           Console.WriteLine("Started Animation-Showing control");
    else
           Console.WriteLine("Started Animation-Hiding control");
}
// Handles event AutoHideAnimationStop
private void dockingManager1_AutoHideAnimationStop(object sender, Syncfusion.Windows.Forms.Tools.AutoHideAnimationEventArgs arg)
{
    if (arg.DockBorder == DockStyle.Left || arg.DockBorder == DockStyle.Right)
        if (arg.Control.Width == 0)
            Console.WriteLine("Completed Animation-Hided control");
        else
            Console.WriteLine("Completed Animation-Shown control");
    else if (arg.Control.Height == 0)
            Console.WriteLine("Completed Animation-Hided control");
    else
            Console.WriteLine("Completed Animation-Shown control");
}
